Letters Patent No. 102,214, dated rip-51 26, 1370.

IMPROVEMEN IN" RAMMER-S'IAVES.

The Schedule referred to in these Letters 'Patent and making part of thesame.

in a. monitor, more advantageously than any now in use.

Figure 1 is a view of the rammer elongated.

Figure 2 is a view of it shortened.

Figure 3 is a section of the same in parts.

It is made of a series of tubes, shutting one within the other.

A, B, and 0 represent these tubes.

D is a knob sorewedint-o the end of the smallest tube.

E is a small length of tube; or it may be a solid cylinder, inserted, byscrewing or otherwise, into the. end of the largest tube.

F is a plug the size of the bore of the tube B, and.

inserted and fastened into the lower or butt end of B.

G is a similar plug, inserted and fastened into the lower end of G.

P is a small bushing, inserted and fastened into the upper end of tubeA, the diameter of the inside of which is the same as the diameter ofthe outside of tube B.

Q' is a similar bushing in the upper end of tube B.

N is a. tube-ring, fastened-on the outside of the lower end of tube B,having an outer diameter the same with the inner diameter of tube A.

O. is a similar ring on the lower end of tube 0.

Through the tube B, near its lower end, and through the plug F, is cut aslot, X, and'in tube 0 and plug G a similar slot, Y.

H H are arms or levers let in at their rounded upper ends into the plugF, so as to turn in their seats, and move in the slot X, and.

J is a spring to throw them out and apart. They have shoulders, V, attheir lower ends.

I I are similar arms let into plug G,and moving in slot Y, havingshoulders at W and a spring, K.

L is a ring moving on tube B, and

M, a ring moving on tube 0.

R- are notches in upper end of tube A, and' I S, similar notches in endof tube B.

The operation is this: I E being, taken out of tube A, and D out of tube0,

O is inserted into B, and B into A. As they are pushed or drawn throughand to their utmost extension, N will strike against I, and 0 against Q,and the arms H H will be driven outward by the spring J, and theirshoulders, taking into the notches R, will hold the tube Bat its lengthontsideof A. In like manner, spring K will act on arms I, and theirshoulders, takinginto notches S, will hold tube 0 distended. D and E maybe replaced. Pushing down ring M over arms I will close them in, so asto bring their outer edges on a line with the interior-of the bushing Q,and the tube 0 may then be pushed into tube B. In like manner, by use ofring L, tube B may be pushed into tube A. The spring-arms may be presseddown by the hand. The pushing in may be done by drawing the rammer back,with the end D against the wall.

'I are small screws to retain ring L on tube B.

This stall is for sponge, rammer, worm-ladle, 859.

What I claim is- 1. The telescopic rammcr-staff for ordnance,constructed and arranged to operate substantially in 'th mannerdescribed.

2. The combination of rings and levers or arms, substantially as and forthe purposes set forth.

In testimony whereof I have hereunto subscribed my name.
